Here i liked the atmosphere, i've been there in the winter (march '13), was cold and rainy outside and then after a shower you enter the bar/orangeraie...it's so cosy, so charming, just to imagine what was Ireland 1 century ago (at least for rich Irish people).
The girls at the reception are nice and helpfull.
The food is, as usual, in Ireland, limited to burgers and fish & chips. Those are not so tasty (apparently there are two kitchens, so fries are coming from one kitchen and the fish from the other, result, one of the two is cold), but again the atmosphere in the Orangeraie restaurant is so nice, you can forgive (a bit) the quality of the food.
The gardens are just wonderfull (but it was raining), enjoy in summertime.
It was very cold in the room and there was no way to get the heating system on, i called the reception, they told me to wait 30 minutes, i told i would put an extra blanket. The bathroom is getting a bit old but is still ok in 2013.
We had a meeting room (for 20pax) reserved in the hotel, the meeting rooms are not very well situated and very difficult to find for the guests. Staff was a bit intrusive as they brought the coffee pots during the presentations disturbing everybody, this is because ther was no space outside the meeting room for coffee break.
